Abstract

The squirrel-cage 17 of the rotor of an asynchronous motor is made by casting aluminium into slots provided in a stack of magnetic laminations. Two kinds of laminations are provided in the stack. One kind comprises a disc 5 having bar-forming slots and ventilation holes 8. The other kind comprises an annulus 13 with a central void and radially extending ventilation slots 11 positioned between bar-forming slots. After casting, the rotor is machined externally to open the outer ends of the radial ventilation slots to provide air flow paths 19. <IMAGE>
